Spider Spiders reproduce sexually and fertilization is internal but indirect, in other words the sperm is not inserted into the female's body by the male's genitals but by an intermediate stage.

- Introduction All living things must reproduce to survive. All body or somatic cells reproduce by mitosiswhich is simple cellular reproduction. All sex cells must reduce their chromosome number as they divide. This reduction division is called meiosis and changes the chromosome number from Diploid, 2n, to Haploid, n. Each offspring resulting from the combination of haploid sex cells will contain the same chromosome number as their parents.

Echinodermata All echinoderms reproduce sexually, and some also reproduce asexually by division of the body into two parts with subsequent regeneration of the missing half (starfish, ophiuroids, and holothurians). Fertilization of the egg and embryonic development occur in the water.

How Do Starfish Mate? Starfish are resourceful creatures that can reproduce in more than one way. Starfish can either spawn together, or they can asexually reproduce- though this isn't the ideal way to produce new starfish because it doesn't promote genetic diversity within the species. While sexual reproduction is a naturally occurring process, asexual reproduction for starfish is usually only the result of dismemberment that results in the formation of two whole starfish with the same DNA.

Copulation takes place when a mature male hops onto the back of a mature female and grips her body with his legs.esert locusts preparatory to mating, London Zoo.

- While most types of sugar ants use mating swarms to reproduce, certain species rely on a process called budding. Ants that reproduce by budding simply separate when the colony becomes too crowded, with one or more queens leading a group of workers (which carry eggs and immobile larvae) to a new nesting site.

Reproduction in Spiders Like all animals spiders reproduce. The biology of reproduction has two sides to it. First there is that anatomy and physiology of the reproductive organs and secondly there is the ecology of boy meets girl. For information on the anatomy of spider reproductive organs you need to see the Spider Anatomy page. For information on behavior scroll on. The reproductive ecology of spiders basically involves three steps, 1) a male has to find a female, 2) then he has to succeed in mating with her, 3) then the female has to lay and protect the eggs.

Tapeworms Tapeworms can reproduce asexually and sexually. Each proglottids contain both female and male reproductive organs. Sperm from a tapeworm will fertilize the egg--either from the same tapeworm or a different one. The proglottid containing the fertilized egg will break off from the body and burst to release the zygote.

How Do Birds Reproduce? Birds reproduce sexually by mating and then depositing shelled eggs, which they incubate, hatch and rear. Birds produce sperm and egg cells just as mammals do, but most male birds lack a copulatory organ. Instead, birds mate through a process known as a “cloacal kiss.”. Continue Reading.

Composting Worm Reproduction: How Worms Reproduce How Red Wigglers Reproduce Most people already know that worms are hermaphrodites. This means that they have both male and female reproductive organs. However, they cannot reproduce alone. They must pair with another worm for successful reproduction to occur. When two worms mate, they join and begin secreting mucus to create a mucus ring around them. After a few hours the worms separate and lay eggs and fertilize the inside of the cocoon. The worms back out of the cocoon and it seals itself off, leaving an oval-shaped cocoon that hardens over time to protect the young hatchlings inside. After 11 weeks, the hatchlings emerge from the cocoon! Worms can’t reproduce just any time. Their bodies undergo changes as they grow older, and at around 90 days old they become old enough to mate. When a red worm reaches maturity, a bulbous gland appears about 1/3 of the way down its body. You have probably seen this on an earthworm or nightcrawler.

Let's Start Out Easy: Propagating Spider Plants Now on to the propagation. Spider plants are very easy to propagate because, when they reach maturity, they put out runners with small plantlets called stolons. These stolons are easy to snip off the plant and grown into entirely new spider plants.

- They can, however, also reproduce by sexual reproduction. Protists reproduce sexually through the processes of conjugation and alternation of generations. Conjugation is a temporary union of protists in which they exchange genetic material. Alternation of generations is a life cycle in which a protist releases spores with half of its chromosomes into the environment, and they form a first generation organism.

Spider Reproduction and Life Cycle Spider Reproduction and Life Cycle. Spider Reproduction. Spiders give off a very powerful type of chemical when they are ready to mate. The males go in search of the males in order to be able to mate with them. They are able to tell not only if the female is ready to mate but if she is of the same species by the chemicals she gives off.

Unit 11- Bacteria and Protists Spirogyra forms nonmotile gametes. Spirogyra undergoes sexual reproduction using a process called conjugation. First two haploid filaments of opposite mating types (+ and -) line up side by side. Each cell then forms an extension that grows towards a cell on the opposite strand. The tubes fuse forming conjugation tubes. The content from the cell of (-) strain travels through the tube and fuse with the cytoplasm of the cell of the (+) strain. The protoplast (the entire living portion of the cell) of each individual organism thus act as an isogamete until they fuse. The diploid zygote develops the zygospore.

Five Examples of Organisms That Use Asexual Reproduction Many species of annelids (worms) reproduce via an asexual process called fragmentation. Included in this category of worms are California blackworms, or mudworms. These worms are hermaphroditic -- they have both male and female reproductive parts -- and can reproduce sexually. However, many times these worms will reproduce using fragmentation.

- Some sponges have sexes, but most are hermaphrodites, or are sexless. A sponge can reproduce asexually through budding. However, most  sponges reproduce sexually by releasing sperm cells into the water  to fertilize ova.The fertilized eggs form larvae that swim away in  search of places to settle.ponges can reproduce sexually and asexually. If a sponge reproduces asexually it does not need a, er, partner. It either budds (a small bud is formed on a sponge before it dr … ops from the sponge and becomes its own new sponge.) or regenerates.

What Is the Life Cycle of a Spider? Quick Answer. The lifecycle of a spider begins with the laying and hatching of the eggs, moves to the development of the spiders and ends with the spider's reproduction, according to Brandeis University.

Insect Many insects, such as grasshoppers can potentially reproduce so fast that they could literally bury the earth in a single season. However there are hundreds of other insect species that feed on grasshopper eggs, and some that feed on grasshopper adults.

How Do Giraffes Reproduce? Quick Answer. BioExpedition explains that giraffes reproduce through mating. Male giraffes are typically ready to mate when they are 6 years old, although more mature bulls often mate first before the younger ones. Female giraffes are ready to mate when they are around 4 years old. Continue Reading.

How do birds reproduce? Birds and ReproductionBirds reproduce by sexual reproduction. Many birds have courtship rituals. Male and female birds from many bird species develop pair bonds. They actually remain with one another throughout the reproductive season. The male bird's sexual organs consist of paired testes.

Reproduction of microorganisms Bacteria usually reproduce by simply dividing in two. Each new bacterium is a clone of the original—they each contain a copy of the same DNA. This is called binary fission (bye-nair-ee fish-un).ome species can reproduce sexually. Some do both. Protozoa reproduce by binary fission, budding or a process called schizogony (skiz-og-uh-knee) . Schizogony is multiple fission: the cell's nucleus divides several times before the cell itself divides into multiple new cells, each with one of those new nuclei.
